Nice. How fast is your home internet connection? I’ve thought about putting an old laptop to this use. But I don’t want my day to day internet to suffer if my site gets traffic spikes. And also, I’m nervous about non-ecc ram.

My internet is very fast for sure (can give more concrete numbers when I am home later) but I don't think you need to worry about it unless you are operating some massive website with huge traffic concurrently.
